This depends on what platforms using systemd will do (if anything) about the information currently stored in /var/log/wtmp on GNU/Linux.
As I understand it, systemd currently has no support for wtmp after 2038, with the idea being that wtmp will go away by then. I also understand that 'last' simply does what GNU 'who' does, so it'll stop working too.
As near as I can tell, journalctl isn't really a substitute for /var/log/wtmp; for that, wtmpdb seems to be the only viable approach that's implemented.
For what it's worth, Debian is looking into possibly adopting wtmpdb; see <https://bugs.debian.org/1043507>. So if we need advice about what Gnulib should do, Sven and Thorsten look like they'd be good people to ask.
